Question details

The user needs to fix an Unlicensed Product error in Office after switching to a new license on the same computer, as the system seems to be caching the old license data.

Product: Microsoft Office
Device & OS: not provided
Scenario: Switching to a new Office license or subscription on a previously activated computer.
Observed behavior: Office displays an unlicensed product message despite signing in with the new account, and there is no visible option to delete the old license.

Before you start

Ensure you have the exact login credentials for the Microsoft account associated with your newly purchased Office license or subscription before attempting to reset the activation state.

Solution 1

Verify Account License Assignment

Check your Microsoft account online to confirm that the new license is actively assigned to the account you are trying to use.

Often, an Unlicensed Product error occurs simply because the newly purchased subscription is tied to a different email address or hasn't fully synced to your primary Microsoft account.

Log into your Microsoft Account

Go to account.microsoft.com in your web browser and sign in with the account you intend to use for Office.

Navigate to Subscriptions

Click on the 'Services & subscriptions' tab at the top of the page.

Verify active licenses

Review the list of active subscriptions. Confirm that the exact license name for your new Office product is listed and active on this specific account.

Solution 2Recommended

Reset Office Activation with the Support and Recovery Assistant

Use Microsoft's official diagnostic tool to automatically clear out the old cached license files and force Office to recognize the new subscription.

Frequently Asked Questions

Why does Office say unlicensed when I have a new subscription?

This usually happens because your computer is still caching the activation data from an older, expired license, or the new subscription is tied to a different Microsoft account than the one currently signed into the Office desktop apps.

How do I check which account my Office license is linked to?

You can verify your license by logging into the Microsoft Account portal (account.microsoft.com) via a web browser and navigating to the 'Services & subscriptions' section to view all active products tied to that email address.

What is the Microsoft Support and Recovery Assistant (SaRA)?

SaRA is an official diagnostic tool provided by Microsoft that helps troubleshoot and automatically resolve common issues, including securely wiping stubborn Office activation caches.

Can I manually remove old Office license files?

Yes, advanced users can use the Command Prompt with the ospp.vbs script to manually view and remove old product keys, but using the automated SaRA tool is generally safer and easier for most users.
